The Jacalin-related lectins ( JRLs ) gene family play a crucial role in regulating plant development and responding to environmental stress. However, systematic bioinformatics analysis of the JRL Gramineae plants has been lacking. In this study, we identified 101 proteins from five species classified them into eight distinct clades. Most AtJRL clustered same group were differentiated proteins. protein motifs, structures domain revealed that genes diverse functions plants. Duplication events indicated tandem duplication significantly contributed expansion family, with most members underwent purifying selection. Tissue expression profile showed OsJRL highly expressed roots, while ZmJRL exhibited high inflorescences. Furthermore, level influenced by drought, cold, heat salt stresses, respectively, implying these important roles response various abiotic stresses. RT-qPCR results demonstrated OsJRL4 was up-regulated under PEG6000 NaCl OsJRL12 OsJRL26 down-regulated PEG6000.

SUMMARY Analysis of salinity tolerance processes in wheat has focused on salt exclusion from shoots while root phenotypes have received limited attention. Here, we consider the varying phenotypic response four bread varieties that differ their type and degree assess molecular responses to changes cell wall lignification. These were Westonia introgressed with Nax1 Nax2 sodium transporters ( HKT1;4‐A HKT1;5‐A ) reduce Na + accumulation leaves, as well ‘tissue tolerant’ Portuguese landrace Mocho de Espiga Branca a mutation homologous gene HKT1;5‐D high concentration leaves. three compared relatively more salt‐sensitive cultivar Gladius. Through use histochemical analysis, ion concentrations, differential proteomics targeted metabolomics, provide an integrated view salinity. We show different metabolic re‐arrangements energy conversion, primary machinery phenylpropanoid pathway leading monolignol production genotype by treatment‐dependent manner alters extent localisation lignification which correlated improved capacity roots cope better under stress.

The DIR (Dirigent) gene family plays a multifaceted role in plant growth, development, and stress responses, making it one of the key families for adaptation to environmental changes. However, research on ZmDIRs maize remains limited. In this study, we identified member family, ZmDIR5, whose promoter region contains numerous elements associated with responses abiotic stresses. ZmDIR5 is upregulated response waterlogging, salt, drought stresses, its protein localized endoplasmic reticulum. Subsequent studies revealed that ZmDIR5-EMS (ethyl methane sulfonate) mutant lines exhibited reduced growth compared WT (wild-type) plants under conditions. also demonstrated relatively higher accumulation malondialdehyde reactive oxygen species, lower synthesis proline total lignans, decreased antioxidant enzyme activity these Additionally, displayed impaired sodium potassium ion transport capabilities, abscisic acid zeatin, expression related genes. mutation inhibited phenylpropanoid biosynthesis pathway maize. These results indicate serves as positive regulator tolerance

Dirigent (DIR) genes play a pivotal role in plant development and stress adaptation. Manihot esculenta Crantz, commonly known as cassava, is drought-resistant thriving tropical subtropical areas. It extensively utilized for starch production, bioethanol, animal feed. However, comprehensive analysis of the DIR family remains unexplored crucial cash forage crop regions. In this study, we characterize total 26 cassava DIRs (MeDIRs) within genome, revealing their uneven distribution across 13 18 chromosomes. Phylogenetic classified these into four subfamilies: DIR-a, DIR-b/d, DIR-c, DIR-e. Comparative synteny with seven other species (Arabidopsis thaliana), poplar (Populus trichocarpa), soybean (Glycine max), tomato (Solanum lycopersicum), rice (Oryza sativa), maize (Zea mays), wheat (Triticum aestivum)) provided insights likely evolution. We also predict protein interaction networks identify cis-acting elements, elucidating functional differences MeDIR genes. Notably, exhibited specific expression patterns different tissues response to various abiotic biotic stressors, such pathogenic bacteria, cadmium chloride (CdCl2), atrazine. Further validation through quantitative real-time PCR (qRT-PCR) confirmed osmotic salt stress. These findings offer resource understanding characteristics biological functions enhancing our knowledge adaptation mechanisms.

Casparian strip membrane domain proteins like (CASPL), exhibit profound associations with root development, stress responsiveness and mineral element uptake in plants. Nonetheless, a comprehensive bioinformatics analysis of the ZmCASPL gene family maize remains unreported. In study, we have identified 47 members at whole-genome level, systematically classifying them into six distinct groups. Furthermore, our revealed that same group contains similar structures conserved motifs. Duplication events showed whole genome duplication (WGD) tandem (TD) contribute to generation together maize, but former plays more prominent role. observed most genes contain MYB-binding sites (CAACCA), which are associated strip. Utilizing RNA-seq data, found ZmCASPL21 ZmCASPL47 specifically highly expressed only roots. This finding implies may be involved development. Additionally, illuminated drought, salt, heat, cold stresses, low nitrogen phosphorus conditions, as well pathogen infection, significantly impact expression patterns genes. RT-qPCR 5/13/25/44 different under PEG NaCl treatments. Collectively, these findings provide robust theoretical foundation for further investigations functional roles maize.

ABSTRACT The heterogeneity of soil salinity is a critical attribute saline agricultural environments, particularly for the physiological adaptability cotton ( Gossypium hirsutum L.) plants. However, mechanisms by which plants acclimate to heterogenous remain poorly understood. To investigate responses seedlings nonuniform salinity, split‐root system using germination paper was employed replicate spatially variable conditions within root zone. endodermal barriers, consisting suberin lamellae and Casparian strip, were found be enhanced in roots on side this relative nonsaline side, playing crucial role maintaining ion balance under heterogeneous salt environment. Ethylene levels higher but significantly lower side. Notably, abscisic acid (ABA) increased both sides. delicate between ABA ethylene can modify suberization, thereby regulating diverse environments.
